8aa57fbed9 edid: turn range limits max pixel clock into an int64_t 
An int32_t is not large enough:
MAX_UINT8 * 10 * 1000 * 1000 > MAX_INT32.

We already use int64_t for di_cta_video_format.pixel_clock.

eed3e1e0f8 test: remove edid-decode as a test dependency 
by storing the reference edid-decode output in the repository. It is now
only a dependency for the gen-test-data target. The CI checks that the
reference output in the repository matches the one generated from a
specific checkout of edid-decode.

ac857e8985 info: use PNP ID database for manufacturer names 
The three character PNP ID is a key to manufacturer name database. It
may be desirable to report the manufacturer's real name than just PNP ID
which can be misleading, e.g. MSI refers to Microstep and not MSI GmbH.

This builds the PNP ID database into libdisplay-info to avoid having to
find and parse files at runtime.

tool/gen-search-table.py started as a copy of Wayland 1.21.0's
src/embed.py and took influence from
10945c4ed8/conv.py
However, our script parses the text file shipped in hwdata package in
Debian (and presumably other distributions) rather than the original
CSV.

00b446d5db test: make edid-decode-diff.sh easier to run 
Having to define just DI_EDID_DECODE was tolerable when REF_EDID_DECODE
does not need setting, but now that there are two built tools, it is
getting inconvenient.

Change the defaults to match the build directory structure and add a new
overridable for the build directory.

Now I only need to set BUILDDIR for this to work. My build dirs are
completely elsewhere, but if someone uses the usual 'meson build'
incantation, the default value for BUILDDIR should be fine.

f70fa58441 test: add high-level API test 
This new test exercises all existing high-level API to make sure the
output does not change unexpectedly.

Unlike with edid-decode tests, these new print tests do not have an
externally defined groundtruth. They are only to detect changes and
exercise code paths.

c930f13457 test: add custom-uncommon-cta-vesa 
This is a hand-crafted EDID taken from edid-decode (test/cta-vesa.test).
It contains uncommon blocks: VESA Display Transfer Characteristics Data
Block and VESA Video Display Device Data Block in the CTA-861 extension.

While it's not as good as a real-world EDID, it can still improve our
test coverage and ensure we behave like edid-decode.
